| Research Abstract |
The metabolism of pyridine nucleotides and related secondary metabolites in higher plants were investigated. A plant specific seven-membered pyridine nucleotide cycle and two bypass enzymes were discovered during the course of the study. Nicotinic acid glucoside formation was restricted to ferns and selected orders of angiosperms, whereas other plants synthesized trigonelline. The pyridine ring of nicotinic acid glucoside was degraded by a novel pathway which involved glutaric acid as anintermediate. The physiological function of pyridine conjugates formation is discussed.
